SIMBL plugin woes after 10.5.3?

Did you get home only to find that Mac OS X 10.5.3 had been released today? Well, just as some users were unpacking and installing the shiny new update, issues with SIMBL plug-ins were discovered. If you have SIMBL plugins installed, then you may have an error show up when you try to launch an application. Past updates on systems with these plugins installed have been known to run into some issues.

If you are experiencing plugin predicaments, there is a way to fix the problem. SIMBL plugins (or other, non-SIMBL InputManager plugins, which may also be problematic) can be installed in any one of the following directories:

~/Library/Application Support/SIMBL/

/Library/InputManagers/

~/Library/Contextual Menu Items/

~/Library/Internet Plug-Ins/

~/Library/InputManagers/

When you see the error in an application, just jot down the name of the plugin and look in those directories for it. When you find the plugin, just move it to a separate folder or toss it into the trash can. The application launch problem should cease.
